The east side of Tokyo Bay is a place that skillfully merges nostalgia with modernity and history with the present and the future. This is on full display in inner-bay areas like Tatsumi, Kasai, and their environs on the east of Tokyo Bay, where new Olympic venues and shitamachi (old town) neighborhoods thrive side-by-side.
This area of the city was once extensive tidal flats. Nowadays, Kasai is one of the few areas where tidal flats remain. Nearby Toyosu, Yumenoshima, Tsukishima, and Tatsumi are the result of land reclamation projects. Of these, Yumenoshima, the site of the Tokyo 2020 archery competition, is the newest.
